【说明】
利用VLAN技术可以把物理上连接的网络从逻辑上划分为多个不同的虚拟子网,可以对各个子网实施不同的管理策略。利用show vtp status命令在某台交换机的特权模式下查看其VTP配置,系统输出的配置信息如图8-10所示。


【问题1】
如果在网络设计过程中划分了很多VLAN,则可采用VTP来简化其管理。交换机管理IP地址只能创建在 (1) 中,而VTP信息只能在 (2) 端口上传播。共享相同VLAN数据库的交换机构成一个 (3) 。不同交换机平台、不同的IOS版本支持的VLAN数量不同,从图8-10所示的输出信息可知,交换机SwitchA允许用户创建的VLAN数最多可达 (4) 个。
